Access arrangements

The terms of an access arrangement need to support fair prices, quality services and choice. The access arrangement defines services to be delivered, service levels to be achieved and rates to be paid.

The Economic Regulation Authority (ERA) negotiates on behalf of the Western Australian community with Western Power before approving an access arrangement. Generally, it is electricity retailers and generators such as Synergy who apply to gain access to the network, so that they can transport electricity to customers.

On 28 February 2019, the ERA published its access arrangement decision for the period 1 July 2017 to 30 June 2022. The ERA's decision and Western Power's proposals can be found on the ERA's website.

The access arrangement covers prices, services, policies and terms and conditions for access to the Western Power network for the next five years. Western Power’s proposal also details its five year investment plan for the period, which will ensure customers can continue to enjoy a good quality of service while network safety, security and capacity is improved.

Prices and policies from the revised access arrangement came into effect on 1 July 2019.
